Long-tailed differential amplifier
Historical background Modern differential amplifiers are usually implemented with a basic two-transistor circuit called a “long-tailed” pair or differential pair. This circuit was originally implemented using a pair of vacuum tubes. The circuit works the same way for all three-terminal devices with current gain. The bias … Ver mais A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. It is an analog circuit with two inputs Ver mais Differential amplifiers are found in many circuits that utilize series negative feedback (op-amp follower, non-inverting amplifier, etc.), where one input is used for the input signal, the other for the feedback signal (usually implemented by operational amplifiers). … Ver mais • BJT Differential Amplifier – Circuit and explanation • A testbench for differential circuits Ver mais The output of an ideal differential amplifier is given by where $${\displaystyle V_{\text{in}}^{+}}$$ and Ver mais An operational amplifier, or op-amp, is a differential amplifier with very high differential-mode gain, very high input impedance, and low output impedance.

The formula for theoretical differential gain is. Adiff = gm ×RD A d i f f = g m × R D. where g m can be calculated as follows:
WebIf all the resistors are all of the same ohmic value, that is: R1 = R2 = R3 = R4 then the circuit will become a Unity Gain Differential Amplifier and the voltage gain of the amplifier will be exactly one or unity. Then the output expression would simply be Vout = V 2 – V 1.. Also note that if input V1 is higher than input V2 the output voltage sum will be negative, and if … WebThe Long-Tail Pair. General.
